When selecting and using a blade dryer, it is necessary to comprehensively consider the actual needs and equipment parameters. Here are some selection and usage guidelines:
Selection:
1. Functional parameters: Based on material characteristics and drying requirements, consider parameters such as impeller diameter, heat transfer area, effective volume, speed, and power of the blade dryer. These parameters have a significant impact on the performance and efficiency of the dryer.
2. External structural dimension parameters: The external structural dimensions of the blade dryer include the internal width of the equipment, the external width of the equipment, the length of the tank, the total length of the equipment, the distance between the inlet and outlet, the total height of the equipment, and the total weight of the equipment. These parameters are related to the installation and footprint of the equipment, and also affect the price of the equipment.
3. Operating conditions: Consider the operating conditions of the dryer, such as the steam working pressure range, the angle adjustment range of the inlet and exhaust air valves, etc. These parameters have an impact on the energy consumption and drying efficiency of the equipment.
4. Supporting equipment: Consider equipment that is compatible with the blade dryer, such as feeding devices, discharging devices, dust removal devices, etc. The selection and use of these devices should be matched with the blade dryer to ensure the coordination and stability of the overall process flow.
Usage guide:
1. Preparation before operation: First, discharge the condensed water in the steam pipeline and close the shut-off valve. Then, turn on the air switch of the electrical control cabinet to start the circulating fans in each heating chamber. Check whether the positions of each valve are correct, and add lubricant to the lubrication parts.
2. Operation process: When the temperature inside the drying room reaches 145 ℃, set the speed control motor controller to the "on" position, and then rotate the speed control knob clockwise to make the pointer reach the desired position. Simultaneously adjust the tightness of the conveyor chain and start feeding the dryer. Pay attention to the uniformity of material discharge at the feeding end.
3. Heating control: Open the gas supply shut-off valve to heat the drying chamber. When the steam working pressure is between 0.4 and 1.0 Mpa, the excellent performance of the machine can be fully utilized. By adjusting the angle of the intake and exhaust air valves, the humidity in the drying room can be controlled to achieve the optimal material drying state.
4. Shutdown operation: When the last batch of materials leaves the dryer, close the steam supply shut-off valve and then turn off all fans slightly later. After the last batch of hollow blade dryers, turn off the main drive, then rotate the speed control knob counterclockwise to zero position, and place the controller switch in the "off" position.
Matters needing attention:
1. During use, the operation status of the dryer should be regularly checked, and attention should be paid to observing the working condition of each component of the equipment. If any abnormalities are found, they should be dealt with in a timely manner.
2. For different material and process requirements, the operating parameters of the dryer should be adjusted according to the actual situation to avoid phenomena such as material overheating or insufficient drying.
3. Regularly maintain the dryer, keep the equipment clean, replace worn parts in a timely manner, and ensure the stability and durability of the equipment.
In summary, when selecting and using a blade dryer, it is necessary to comprehensively consider factors such as equipment functional parameters, external structural dimensions, operating conditions, and supporting equipment to ensure that the blade dryer can meet actual needs and maximize its effectiveness.
